What Can a 2,000W Inverter Run in a Van or RV?
A 2,000W pure sine wave inverter covers the vast majority of what van lifers and RV users want to run from battery. Here's exactly what fits, what's borderline, and what won't work.
For inverter sizing in general: what size inverter do I need?. For installation: how to install an inverter in a van or RV.
What a 2,000W inverter runs easily
These all draw well under 2,000W and a 2,000W inverter handles them without strain:
| Appliance | Typical watts | Notes |
|---|---|---|
| Laptop (charging) | 45–90W | Essentially zero impact |
| Phone charging | 5–25W | Negligible |
| Tablet | 10–30W | Negligible |
| LED TV (24–32") | 30–80W | Fine |
| CPAP (no heat) | 30–60W | Fine; pure sine required |
| Electric blanket | 100–200W | Fine |
| Small fan | 20–50W | Fine |
| Drip coffee maker | 600–1,200W | Fine for a 10-minute brew |
| Single-serve coffee (Keurig/Nespresso) | 1,200–1,500W | Fine for 1–2 minute brew |
| Blender | 300–600W | Fine |
| Toaster | 800–1,200W | Fine for a few minutes |
| Induction cooktop (medium setting) | 600–1,200W | Fine; use a 2,000W inverter for headroom |
| Hair dryer (low heat) | 500–900W | Fine on low; high setting may hit limits |
What's at the limit
These loads are technically within a 2,000W continuous rating but push the inverter and require a good battery bank:
| Appliance | Typical watts | Reality check |
|---|---|---|
| Induction cooktop (max setting) | 1,500–1,800W | Leaves little headroom; use nothing else simultaneously |
| Hair dryer (high heat) | 1,500–1,800W | Same — nothing else running |
| Small portable air conditioner (5,000 BTU) | 450–600W running, 1,500–2,000W startup surge | The surge is the issue; needs a high-surge inverter |
| Small electric space heater | 750–1,500W | Works but drains the battery very fast |
What a 2,000W inverter won't run
| Appliance | Why not |
|---|---|
| Full-size RV rooftop AC (13,500 BTU) | 1,200–1,800W running + 3,000–6,000W startup surge — exceeds a 2,000W inverter |
| Electric water heater | 1,500–4,500W continuous — possible at low wattage but impractical |
| Full-size microwave (1,000W+ cooking power) | Draws 1,500–1,800W from the wall — right at the limit with nothing else running |
| Electric dryer | 4,000–6,000W — not a van appliance |
The battery matters more than the inverter
A 2,000W inverter can only deliver what the battery can supply. At 2,000W output with 85% efficiency, the inverter draws ~2,350W (196A) from a 12V battery. A 200Ah LiFePO4 bank at that draw rate would last less than an hour.
In practice:
- Cooking: 20 minutes at 1,500W = 500Wh — your 200Ah bank handles this easily and refills from solar
- Coffee: 10 minutes at 1,200W = 200Wh — trivial
- Laptop all day: 60W × 8 hours = 480Wh — easily covered
Van inverter use is almost always brief, high-watt bursts rather than sustained high-draw loads. A 200Ah LiFePO4 bank paired with 200–400W of solar handles typical van inverter use without issue.
Surge vs continuous rating
Most inverters are rated for both continuous watts and surge watts (typically 2× the continuous for a few seconds). Appliances with motors — blenders, AC units, some power tools — have a high startup surge that can exceed their running wattage.
A 2,000W continuous / 4,000W surge inverter can handle a small AC unit's startup even though the running load is under 2,000W. Check the surge rating before assuming an inverter can start a motor-driven load.
Recommended 2,000W inverters
- Renogy 2000W Pure Sine (~$200) — the value pick; widely used in van builds
- Victron Phoenix 12/2000 (~$500) — premium quality, Victron ecosystem integration
- Victron MultiPlus 12/2000 (~$650) — if you want built-in shore power charging too
